STREET-SWEEPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 265,537, dated October3, 1882.

Application filed Mayi), 1882. (No model.)

To atl 'whom tt may concern: i

Beit known that I, CHARLES Z. ONEILL, of the city, county, and State of'New York, have invented certain new and useful Improvements inStreet-Sweeping Machines; and I do hereby declare that the following isa full, clear, and exact description thereof', reference being had tothe accompanying drawings, and to the letters of reference markedthereon, makin g a part oi this specification.

My invention relates to street-sweeping machines, and has for its objecta more perfect adaptation of revolving brushes to the Work of removingthe dirt from the street and leaving it in windrows at one side ofthemachine, so as to produce an easier-running machine under more readycontrol of the driver than those heretofore in use.

[tconsists mainly ofabrush-wheel constructed of a series of brushessecured concentrically upon adisk revolvingin a horizontal plane upon avertical shaft couuterbalanced to admit of an adjustment of the pressureof the brushes to the requirements of the work, and mounted upon auniversaljoint, permitting the brushes to adapt themselves to theinequalities of the street. It embraces also details in the constructionof the machine serving to increase its efliciency, as hereinafter fullydescribed.

In the accompanying drawings, Figure 1 is a vertical section of myimproved streetsweeping machine; Fig. 2, a transverse section in theirregular line x 00 of'Fig. l; Fig. 3, a transverse section through theaxle, immediately inside of one of the wheels; and Fig. 4, alongitudinal section through the wheel-hub, illustrat-ing thecombination of a ratchet-gear therewith; Fig. 5, a transverse sectionthrough the axle inline with one of its journal-bearings,- illustratingmy lubricating device therefor.

A is the frame of my machine, supported upon the axle B by means ofsuitable journaL, boxes, (J, secured to its under side, as shown in Fig.5.

D is a large horizontal disk orsweepingwheel, suspended from'la verticalshaft, E,jour naled in a cross-bar, A', ofthe frame and in a rectangularbracket-arm, F, secured to said cross-bar, to depend therefrom as shownin Fig. 1. The disk D is armed upon its under side with a series ofbrushes, G G, arranged to project downward therefrom in concentric rows.(See Fig.land dotted lines, Fig. 2.) 1t is connected to the verticalshaft E by means of a trausversely-slotted head, H, secured to the lowerend of the shaft, and a pin, I, passing through said slot and fixed ateither end to lugs It lr, projecting upward from a plate, J, secured tothe center of the disk. The slot is so enlarged as to permit a freeoscillation of the disk and pin upon the shaft, while the transverse pinis so conhned laterally that the rotation ofthe shaft will becommunicated by means of the pin to the disk. the shaft .E and itssweeping-wheel D is produced by means of a bevel-pinion, L, upon asleeve fitted upon the shaft above the bracket.A

F, and connected thereto by a spline, and which gears with abevel-pinion, M, upon a countervshaft supported in a hanger, F,dependent from the frame upon one side of the shaft E, the pinion Nbeing itself geared by spur-wheel N to the main axle B, as shown in Fig.l. A loose collar, P, is interposed between the beveled pinionL and thecross-bar A above. The

The rotation ot' spline upon pinion L permits the shaft E to movelongitudinally upon its axis, so that it may be readily elevatedordepressed. rEhe elevation of the shaft E and sweeping-wheel D iseffected by means of a lever, R, pivoted to a short upright standard, S,secured upon the cross-bar A of the frame, immediately in front of theupper end of the shaft E. The short arm of the lever R is forked toembrace a loose collar, a, placed vupon the shaft, and to engage pins bprojecting therefrom, the loose co1- lar a, being confined by means of asecond collar, c, fixed to the shaft by means ot' a setscrew. (See Fig.l.) The upper side of the long arm of the lever R is serrated. Acounterbalance-weight,T, is arranged to slide freely back and forththereon, and a pin, U, adapted to drop vertically through an aperture inthe upper side of the weight to engage the notches therein, serves byitsgravity to lock the weight at any point on the lever at which it maybe set. By this means the pressure ofthe brooms or brushes upon thestreet may be vertically adjusted at pleasure by simply lifting the pinU and moving the counterbalancing-weight T in or out upon the lever R.The use of the IOO gravitating lock-pin U dispenses wholly with allsprings, gears, pawls, and chains in this connection and serves to ixand maintain the adjustment ot the machine with ease and precision.

A 'fender consisting of cross-bar Q, (see dotted lines, Fig. 2,) adaptedto move vertically upon guide-rods V V, suspended from the frame, (seeFig. 1,) and which is fitted either with a set of broomsvor brushes orwith a vertica-l foot-plate, is supported at the rear ot' the machine,upon the side thereof, so that its inner end shall touch the brooms orbrushes on the periphery ofthe sweeping-wheel D and extend out therefromradially or tangentially, as shown in Fig. 2, so as to arrest and divertthe dirt and dust swept back by the rota-tion of the wheel and force itto one side. The fender Q, is made adjustable as to height by means ot'an upright rod, \V, extending up through the frame between theguide-rods V Y. A plate, d, Fig. 1, pivoted eccentrically to the side ofthe rod between a collar, c. on its upper end and the frame of themachine, and which is turned by means ot'an arm, f, projectingtherefrom, serves by its movement to lift the rod W or allow it to drop,as occasion may require.

The driving-wheels K are coupled to the driving axle by means otlpawl-and-ratchet gear, which permits their independent lnotion whenrunning backward, the ratchet heilig fixed upon the axle and the pawlpivoted to the inner' i'ace ot' a ange, f1', upon the inner end of thehub, so as to engage the ratchet g. The pawl differs from those usuallyemployed in this connection, in that it is in the i'orul ot' a bentlever pivoted at its angle, as shown in Fig. The engaging-arm lL is madeto bear upon the ratchet-wheel g by means ot'a spring. Its free arm L isthrown forward to lift the engaging-arm clear of the ratchet-teeth bymeans ot' an arm, m, upon the end of thc pivot-rod I, (see Fig. 4,)extending` through the side ofthe flange t', and which terminates in ashort lever or handle, m, projecting outward radially parallel with theouter face ofthe flange By turning this lever m the end of the innerarm, m, is brought to bear against the free arm h' of the pawl, so as toproduce a disengagement 0f the pawl from the ratchet. The driver maythus readily disconnect the wheels from the driving-axle by a simplemovement of the lever m.

I do not herein claim the form of ratchetgear by which thedriving-wheels are coupled to the driving-axle, as I contemplate makingsaid devices, as described, the subject ot' a sep arate application forLetters Patent.

That I claim as my invention is- The con'ibination, in a street-sweepingmachine, with its frame, and with a horizontal sweeping-wheel supportedthereby and adapted to revolve in a plane parallel with the streetlevel,of a vertical shatt having longitudinal pla-y in its bearings,connectedto the wheel by a universal joint and suitably geared to thedriving-axle ot' the machine, an adjusting-lever adapted to engage thewheel-shaft and counterbalanee the weight of the sweepingwheel, andalateral fender dependent from the frame ot' the machine atan angle withits line of movement, so thatone end shall be in contact, or nearly so,with the circumference ofthe adjustable rotating sweeping-wheel and theother extend therefrom radially or tangentially toward the rear ot' themachine, all substantially in the manner and for the purpose herein setforth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. l

CUS. Z. ONEILL.
